Installation Instructions

8.3 Adding Refrigerant

In North America, the standard pipe length is 7.5m (25ft). The minimum length
is 10ft. The factory charge is suitable for pipe lengths of 10 -25ft. If piping length
exceeds 25ft, the additional refrigerant to be charged can be calculated using the
formula in Table 8. For multi-zone units refer to the multi-zone installation and
operation manual.
